Stovax Riva2 66 Inset Fire Riva2 66 Frame Options:Riva2 66 Profil 3 sided Frame Robust heavy duty steel plate Robust heavy duty steel plate and cast iron construction (115kg of it) Since the Hobbit SE was originally designed primarily for installations in single story temporary buildings it features a 100mm (4') flue outlet which helps to create the optimal updraught for safe operation with a shorter flue stack the Stovax Riva2 66's environmental credentials are impeccable and are well below the standards required by the tough Ecodesign Regulations so that you can be sure that when you choose this stove to heat your home with sustainable wood logs you're not only significantly reducing your homes's carbon footprint but that you're also going to minimise the impact heating your home will have on the environment and your local air quality One fairly unique feature of the Stovax Riva2 66 is that you can also easily add a warm air ducting system to it from its two top outlets to distribute its generous heat within a larger living space or to two other adjacent rooms
